In Figs. REF  and REF  we summarize our results for the case of a stellar-mass and intermediate-mass black holes, \(M_{\rm BH}=10\, m_{\rm wd}\)  and \(M_{\rm BH}=10^3\, m_{\rm wd}\) , respectively. We show the electromagnetic radiation power of a binary system as a function of time, restricting ourselves to two lowest multipoles. We also include the frame (the bottom one) which depicts the incoherent sum of electric dipole and quadrupole contributions. Actually, we also added the contribution from the magnetic dipole term, assuming it is equal to that related to the electric quadrupole one (this assumption seems to be reasonable since both terms appear at the same level of multipole expansion). Ten periastron passages, equally separated in time, can be easily recognized. Clearly, bursts of radiation emerge while a white dwarf is coming through the periastron. Such regular emergence of radiation bursts resembles recurrent flaring of X-ray sources reported recently [1]}, [2]}, [3]}, [4]}. The amount of dipole radiation exceeds the quadrupole one by an order of magnitude for a stellar-mass black hole case, Fig. REF  (first outburst, in fact, is excessively high, due to a kind of numerical turn-on effect), but the opposite becomes true for an intermediate-mass black holes, see Fig. REF . The total radiation (bottom frames in Figs. REF  and REF ) understood as the incoherent sum of lowest order multipoles, including the magnetic dipole term, shows regular bursts as well.
